Why is it important to watch out for motorcycles while driving?

Answer: B — They are difficult to see

It is crucial to watch out for motorcycles while driving primarily because they are often difficult to see. Motorcycles are smaller and less visible than larger vehicles, which means they can easily be in a driver's blind spots or obscured by other traffic. This reduced visibility can lead to accidents if a driver is unaware of a motorcycle's presence, especially at intersections or during lane changes. While it is true that motorcycles can turn quickly, travel at higher speeds, or may sometimes operate without mirrors, these factors are secondary to the overarching concern of visibility. The smaller profile of a motorcycle combined with their agile maneuvers emphasizes the necessity for heightened awareness from drivers of larger vehicles, ensuring safer road conditions for everyone.
